摘要： Stainless steel suitable for use as water turbine elements for water power plants having high cavitation erosion resistance, comprised of at least one of either carbon of no more than 0.2 weight percent or nitrogen of 0.02-0.3 weight percent, together with silicon of 2.0 weight percent or less, chromium of 10.0-20.0 weight percent, nickel of 0.5-10.0 weight percent, manganese of over 2.0-20.0 weight percent, and the balance of essentially iron, and in which the ferrite phase has not been formed but where at least either the epsilon phase or the austenite phase has been essentially formed.
